So, what is the difference between L-glutamine and glutamine peptides you ask. Well, the main difference between the two is that L-glutamine is "free form". This means that it is "free" from being bonded to other amino acids, which makes it less stable. It is still quite beneficial though. Glutamine peptides on the other hand are not "free"; instead it is bonded to other amino acids with peptide bonds. This makes it more stable and better assimilated by the body.

You may want to find a product that combines both L-glutamine and glutamine peptides. This would help ensure good uptake, absorption, and stability in the body.

It is believed that glutamine peptides may have immunomodulatory, anticatabolic/anabolic, gut mucosal barrier-protective and antioxidant actions.

There are no known reports of overdose with glutamine peptides. There have been rare reports of people having constipation and bloating with high doses of glutamine peptides. They are contraindicated in those hypersensitive to any component of a glutamine peptide-containing product.

People with renal and liver failure should be very cautious in the use of glutamine peptide supplements. If you are pregnant or nursing you should avoid the use of oral glutamine peptide supplements unless otherwise directed by your professional healthcare provider.

NOTE: Regular L-glutamine products are different and are not listed on this page.
